Application filed Jannary can bodies and heads will be automatically:

deliveredtothe seaming mechanism, the double seaming operation completed and the work discharged from the machine; and the; productionfrom which willbe much greater than is feasible frompresent types ofmachines adaptedto perform the same work. i 1

The manner in which I accomplish my object is illustrated in the, accompanying drawings, which are in a certain sense illustrative only in that they show but one embodiment of my invention. In these drawings, Fig. 1 is a front elevation of abottom double seaming machine, partly in section. Fig. 2 is aleft end elevation. Fig. 3 is a right end elevation. Fig. 4 is a cross section along the line on 1, looking in the direction indicated by the darts. Fig. 5 is a cross section along the same line but looking in opposite direction. Figs. 6 and 7 are details of the seaming rolls and the slides on which they are mounted. Fig.' '8 is a perspective view of one of the sleeves forming a part of the head feeding mechanism. i I

The same reference characters refer to the same parts throughout the several views.

, The drawings show a simpleform of my invention, a machine which is adapted to double seam in but one head of a cylindrical can. This machine comprises a base or table 2, supported on leg members 3, in which is journaled a driving shaft 4:, which may be driven from or by a pulley 5. or in any other suitable manner. J ournaled in the base or table 2, is a counter-shaft 6, driven from the shaft 4 by means of the spur gears 7 and 8. u i Supportedby the table'2, are end brackets 9 and 10, in which is journaled a shaft 11, driven through a chain of spur gears 12, 13, 14:, and 15, from thecounter-shaft 6.

Fastened on the shaft 11, soas to rotate therewith is a hub member 16, in or on which are mounted a series ofradially and circumferentially spaced rotatable shafts or spindles 17 one end of each having formed thereon or attached thereto. a mandril 18 adapted to engage the work and to coact with the seaming rollers 19 to form the 31,1925. Serial he. seas.

seam. The seaming rollers 19, are mounted oncarriers 20, 's'lidably mounted in or on the member 16. The rollers 19 are prefer- :ably run on suitable roller bearings and are so attached to the, sides to be readily detachable for replacement.

i Eachof the carriers 20, is provided with a stud 22 or- 22 on which is acam engaging roller23 or 23 adapted to engage in camgroovesformed 1n the cam plate 25,

them in" contact for therequired period of time, then retract them to starting position,

all at the proper times.

Loosely mounted on the shaft 11, and so connected together that they rotate as a unit, isa pair of gears 26*, and 27, which are driven through an idler gear 28 by a fastened on the rear end thereof and all of thesepinions areinmesh withthe gear 27 so that rotation of said gear will cause counterrotation of the pinions and the spindles Y radially and cir cumferentially spaced bearjing sleeves32, journaled in which are shafts or spindles33, on the forward ends of which are formed, or fastened, work-engaging discs or members 34. The spindles 33 are concentric: with the spindles 17 mounted in the member 16, and aredriven by means of pinions 30 meshing with lthe gear wheel "27 driven through the gears 26, 28 and 29 ,from the counter shaft 6. The speed and directionof rotation of each concentric pair of spindles are to be identical, but the means for. imparting rotation thereto may be different from that shown and described.

The bearings 32, slidable in the member 31, are adapted tobe advanced and retreatedat proper times by means of the plungers 39fattached thereto and which are provided with cam engaging rollers 38, adapted to engage the cam groove 36 formed in the cam ring 37. Force to drive forward the bearings 32,"is applied or transmitted through a spring 40, thus providing a possible yielding which will care for variations in the cam lengths due to the progressof the seaming operation, or other likely variations, and so theseca'm grooves being-adapted to actuate i the sl des 20, so as to advance the rollers JDtO operative contact with the work, hold spur gear 29 fastened on the counter shaft 6. Each ofthe spindles 17 has a pinion 30,

insure the needful firm grip on the Work at all times when the same is being actedupon by the rollers. g V H While no great amount of ad uStments in the relative positions of the mechanism described in the paragraphs immediately preceding, and that describedinthe three paragraphs which immediately precede those, is possible in the machine illustrated,

itisof course obvious-that one or both of these groups ofinechanism could be mount- -ed on a sub "base so that the relative posi tion" of onein relationto-the other could be readily adjusted; thus making one machine capable of handling cans of different lengths. it is; also" obvious that thehub memberslG and 31could-be combined or made'as a unit when the machine is required to handle but onelength'of can. 7 It is also 7 obvious that; where two] hub members are used the recessed parts thereof (in which are the work receiving recesses 160 v and ";3 10):may be made removable so that they may, be replaced by parts adapted to receive cans of a difierent diameter. The work- 7,

engaging parts would of course have to be changed=to correspond, as would also the bottomxfeeding mechanism. j

IAlljof the spindles, l7 and-38, are preferably mounted in suitable roller bearings, but as this is standar'd practicethey have not been sliown inthe drawings. V

The positlonofthe cam-engaging rollers 23. and 23 in relation to the seaming rollers l9, mnst be adjust-able if the machine 7 is to handle cansof different diameters, and they are preferably ad uStable to some extent oii all' machines of this type.

20 is slotted through into the opening adapted to receive the base portions of the-studs and '22 ,anda longitudinal rod 70, in

the side of whichisa notch 70, isinserted as illustrated. The roller bearing portions i 9 and 221, oft-he studs 22* and 22 are formed. eccentric with the base portion so that rotation of the stud. will vary the '10- cation of the cam rollers. The notch 70 is adapted to pass the seaming roller studs 19 so that when the nut on the upper end ofthe rod is tightened, both the studs 19 and the stud 22* (01722 will be firmly clamped in adjusted positions. 4

lviounted in front of the member 16, or if but single hub member is-used that end thereof which :carries the mand'rils and seaming rollers, is a trough like structure adapted to receive 'the initially formed heads (tops or bottoms)- to' be fed into the work engaging mechanism by the automatic head feeding mechanism. This trough'is here illustrated as comprising a bracket-like member 41, through which is an opening e20 adapted to pass the heads, which are 7 7 In the machine illustrated this adjustment s provided for as illustrated in Fig. 6. The slide forced towardthis opening in a-manner whiclrwill behereinafter described, and a number of rods 41, 41 4:1 41, and 41 the opposite ends of which are supported by'a" bracket arm 42, from' a convenient part of the frame of the machine. V r

Slida'ble respectively on the rods 41 and l-1 ,'-are the sleeves and @3 each of 1which is provided with wing 43 adapted to be brought'into contact with theback of a packof heads sons to hold them ina vertical "position in the feeding trough. Each of'these sleevesis also provided with a handle whereby it maybereadily. grasped by the operator so asto position it when desired, and each is fastened to a" cable '47, to which is attached a weighted normally 'drawingsaid sieeve iand the. p acltpf heads 1 if the wing be in contact therewith, toward the feed opening 420; Each ofthese sleeves is also provided with a projection 43", which may be turned in behind a hook 4% on the bracket arm a2, so: as to hold the sleeve at thatend ofv the trough. 1

48', lies closely againstjthe 1i feeding: dial face of th e' bracketdl, and is. =pro-videdwith hook like recesSes l-S is adapted to remove b ttoms one at a time from the pack 56 in the feeding trough and to deliver them in front of the mandrilsitl. The feeding dial is provided with a cover platev (not shown) which prevents the-bottoms from escaping from thefeeding mechanism 1mtil they fare picked out by the. mandrils 18.

Can bodies are" delivered to the machine by gravity, coming downa slide as inclicated at 53, and dropping into the recesses in v the members 16 and 31, Afterthe com pletion of the double seaming operation the cans drop out into a chute or slide as indicated at 55in Figs. 2 and 4.

The operation of my improvedv double seaming machine is asv follows: Whenthe machine is in operation bottoms are removed one at a time from the pack 56 and delivered :into' the recesses in the members 16 and in front of the mandrils 18, which engage with the bottoms and carry themout of the, feeding mechanism, bnt just prior to the completion ofthis operation a can body dropsinto the' recessandin' front of the bottom. Atthis time 13118703111 groove Work to drop out onto the chute orgslide 55. Should the work be, inclined torvcling to-the mandrils, the spring actuated kick-outs 21,

which are pressedb'ack by the forward grip-3 ping movement of the sleeves 32 and the rollers during most of the time thatit is travelling from the entry pointto the point at which it is expelled from th machine;

" and when the machine is being operated at longitudinally slidable sleeve a speed which will seam in the heads of a given number or cans per minute,the mandrils and seaming rollers need to revolve at a speed equal to only about-flone quarter the speed of those parts on present machines having an equal rate of production,

and this comparatively slow speed insures a longer life to those parts which are customarily renewed at intervals.
